I think it would be very useful if there was a feature where I would receive an e-mail when a hack has been updated. I don't want to receive updates when every single person makes a reply (subscribe to thread) but just when the hack has been updated.

There is already a feature that lets hack releasers to send an update to users that installed the hack by e-mail.

Whether they used it or not, there's nothing we can do about it. :)

Would you like to get an e-mail every time the first post is edited, or the releaser posts a reply, or what?
I might consider it.

I think that getting an e-mail when the first post is edited would help. Does anyone else have any feedback on this?

If they make updates, (editing the first post), then they just use the send update feature to notify people who have installed the hack.
